Dmax is a hell of a puller, aka, I smoked my trailer brakes

[Balance_Of_Judg]

so much power I didnt even notice the breakaway plug got pulled and locked up the brakes on the camper!
was on a camping/fishing trip with the family
dont know how it happened. was in when we left the camp ground. pulled in the driveway, smelt burning brakepads and saw smoke
coming from the camper wheels

was still getting 14mpg towing tripple with the locked up 28foot camper and 20foot fiberglass CCboat
sooo...what do you suppose I will need to replace? breaks still seem to work, not sure how much pad I have, wheels still seem to spin freely

I've heard it all now! Dude that truck is worth a fortune with the kind of mpgs it gets. What do you get empty? Must have one of those 30 mpg Duramaxes!!

19MPG unloaded at 60MPH hand calc:R

oh, and I would love to know where you got that it was a 4000lbs boat...

Sounds about right.
On the boat, I guessed by CC you meant Correct Craft, as in Nautique. 20' ski nautique, little under 3k lbs + trailer = about 4k lbs. 20' Air Nautique of some flavor, over 3k lns + trailer = maybe 5klbs total. SHouldnt be too far off there!:R

I must need to move back to the midwest or something. You and the guy with the cummins pulling the other tripppple getting 14mpg at 60mph while smoking the trailer brakes are getting phenominal mileage!

I didn't think about him saying he got 14 with dragging brakes, sorry. I can get it easily with brakes working correctly. I average 19.5 everyday mix empty and 22+ on the empty road trips @ 75 mph. At 60 empty I'm close to 27 mpg.

Mine pulled out once and I immediately knew it. No move. I won't move if there is even a little pull back from trailer. Has nothing to do with how much power you have.

If the wheels were spinning the brakes were NOT locked.

Locked up means just that, shoes locked to drums, wheel not turning. Sounds like nothing more than a heavy drag!

Sorry about you worn out brake shoes, likely destroyed drums.

I can get that with my Cummins and running 60 and I'm pulling more load than he is. I don't see the problem with his numbers.

OP your brakes were just dragging not locked because if they were locked you would definitely know it. You had problems before this problem. I would pull the drums and inspect for heat damage. If it were me I would just replace the backing plates. You can buy them already loaded with all the hardware ready to install. Check the drums for cracks.

Your trailer brakes were energized with full battery voltage.
They engaged but didn't lock up otherwise the wheels would not have been spinning.

Worst case......new drums, new brake assemblies and new bearings

You will need to inspect each wheel (brake/bearing assemblies).
Brake shoes worn out
Drums scored
Brake magnets damaged from full voltage
Bearings/races scored from high temp
Bearing grease burnt up
Spindles scored

Tires flat spotted

Hey you said you were pulling triples and you listed only two trailed what was the third. 🙂

MN law refers to towing triple as a three vehicle combination including the TV.

You are right about that. I think the next time I am out I will try to get my trailer brkes to lock so the mileage will go sky high. all the OP forgot was to start that yarn with once upon a time. :B

$300 per axle to make as new if you do it yourself.
